GNSS Receivers for Japanese GSI GeoNet Network

Trimble (USA) is to supply more than 500 Trimble NetR9 GNSS reference station receivers to the Geospatial Information Authority of Japan (GSI), part of the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), to modernise its nationwide GeoNet GNSS-based network. The receivers were purchased through the Nikon-Trimble joint venture in Japan.

GeOnet为各种应用提供GNSS数据，包括测量，建筑，映射和GIS，天气预报和许多其他应用程序。该网络还用于监测地球的地壳运动，以帮助研究日本的地震活动。

Ulrich Vollath, general manager of Trimble’s Infrastructure Division, said that Trimble, in cooperation with Hitachi Zosen Information Systems (HZS) of Japan, has supplied more than 2,700 GPS/GNSS reference stations to GSI since 1992. The GPS data from the NetR9 GNSS reference stations will support the existing monitoring system, which uses Bernese processing software in a quasi real-time mode, and also provides the real-time raw data from a subset of GeoNet stations to produce the network corrected Real-Time Kinematic (RTK) data service for the entire country. As part of the network capabilities, surveyors can access accurate control points and data through an online bulletin board service.
